INTRODUCTION

The use of Central Venous Catheters (CVCs) has increased dramatically over recent years. Once seen

only in critical care areas, these catheters are now commonplace in the medical/surgical and

community environment. Depending on the patient’s needs, there are a variety of central venous

catheters available. A CVC can be inserted for short-term or long-term I.V. therapy.

Central Venous Catheter management requires evidence-based, best practice standards to minimize

complications and maximize patient outcomes. CVC management is a specialized skill performed by IV

practitioners who have demonstrated the required competencies.

Purpose This self-learning module will provide you:

Information about CVCs

Information about nursing care and management of CVCs in the adult patient

Information on complications associated with CVCs

This self-learning module along with return skill demonstration will assist you in

meeting the competencies of CVC management.

Please see Appendix A (Responsibility for CVC management)

Learning Instructions The learning activities in this self-learning module are based on the objectives and will help you to

understand and apply what you have learned. It is recommended that you complete the learning

activity after each section.

If you are using this self-learning module for the purpose of review, you may wish to attempt the

learning activities first to find out what material you need to review.

What is a Central Venous Catheter?

Central Venous Catheter (CVC) – [also known as a central line or a Central Venous Access Device

(CVAD)] A CVC is an indwelling device that is inserted into a vein of the central vasculature. CVCs are

being used increasingly in inpatient, outpatient, and community settings to provide long-term venous

access. CVCs disrupt the integrity of the skin, making infection with bacteria and/or fungi possible.

Infection may spread to the bloodstream and hemodynamic changes and organ dysfunction (severe

sepsis) may ensue, possibly leading to death. (Center for Disease Control and Prevention, 2011) (Hunter &

Hunter, 2012) (Safer Healthcare Now, 2012) (Provonost, et al., 2006)

CVC insertion puts the patient at risk from a number of complications and unintended outcomes, at the

time of insertion, after insertion, and upon removal. These include pneumothorax, hemothorax, cardiac

tamponade, cardiac perforation, cardiac arrhythmias, erosion of the vessel wall, occlusion, infection,

and catheter dysfunction.

There are 2 CVC type classifications: Short-term CVCs and Long-Term CVCs, which includes Implanted

Venous Access Devices (IVAD), Peripherally Inserted Central Catheters (PICC), and Tunneled CVCs

(Alexander, Corrigan, Gorski, Hankins, & Perucca, 2010) (Bishop, et al., 2007) (Infusion Nurses Society, 2011)

(Infusion Nurses Society, 2016).

Indications for Use Administer intravenous fluids and blood products

Administer medications

Administer hypertonic solutions (Total Parental Nutrition [TPN]), vesicants (e.g. chemotherapy),

irritants (e.g. cloxacillin), and solutions with extreme pH values (e.g. vancomycin).

Obtain venous blood samples

Provide long term intravenous therapy

Administer large volumes of intravenous fluid quickly

Administer vasopressor or vasodilator therapy (e.g. dopamine)

Monitor central venous pressure (CVP)

Provide access for transvenous pacemaker or pulmonary artery catheters

Access venous circulation when a patient has difficult or impossible peripheral access

Provide hemodialysis access

Ideal CVC tip placement should be patient-specific for the intended use of the CVC. High flow

catheter function, such as permanent tunneled hemodialysis and pheresis catheters, can be improved

by placing the catheter tip in the upper right atrium. Multiorifice CVCs used for venous gas aspiration in

the case of a gas embolism are the only other indication for which a CVC tip may be placed within the

right atrium. However, the majority of patients who require CVCs do not need these capabilities and a

CVC for more routine vascular access indications (such as medication delivery, fluid delivery,

and TPN) will work well with a CVC positioned within the lower segment of the SVC at the cavo-atrial

junction (CAJ) or the inferior vena cava above the level of the diaphragm for femorally placed CVCs.

(BC Renal Agency, 2013) (Campisi, Biffi, & Pittiruti, 2007)(Dariushnia, et al., 2010) (Forauer, 2007) (Gebhard, et

al., 2007) (Hamilton & Foxcroft, 2008) (Pittiruti, Hamilton, Biffi, MacFie, & Pertkiewicz, 2009) (Shamir & Bruce,

2011) (Vessely, 2003) (Yoder, 2001)

Actual tip placement should be confirmed as soon as possible after insertion, before use, and whenever necessary

(CVC measurement has moved from original measurement either in 2cm or greater or out 4cm or greater,

disappearance of the venous pressure waveform (may indicate vessel perforation), or upon receiving a patient where

initial CVC measurement and confirmation of placement are not available or provided. (Forauer, 2007) (Gebhard, et

al., 2007) (Hamilton & Foxcroft, 2008) (Infusion Nurses Society, 2016) (Shamir & Bruce, 2011) (Vessely, 2003)

(Yoder, 2001)

Tip confirmation may be done by chest x-ray, fluoroscopy (BC Renal Agency, 2013), monitoring of venous

pressure waveform, real-time ultrasound with ECG (PICCs), or, in the case of femorally placed CVCs, by

drawing an arterial blood gas from the CVC and confirming it is a venous sample or by CVP waveform

analysis. (American Association of Critical-Care Nurses, 2007)

**Not a suitable location for a PICC

Types of Central Venous Catheters

Short-term (Percutaneous, Non-Tunneled, Non-Cuffed) Short Term

PICC (Peripherally Inserted Central Catheters) Long Term

Tunneled Catheters Long Term

Implanted Venous Access Devices (IVAD) Long Term

Short-Term CVC – [also known as a percutaneous CVC, non-tunneled CVC, or percutaneous

sheath/introducer)] A CVC inserted by puncture directly through the skin and to the intended location

without passing through subcutaneous tissue. (Infusion Nurses Society, 2016) Site placement is typically

in either the subclavian vein or the internal jugular vein, though it may also be inserted into the

femoral vein. If the CVC will be needed for greater than 2 weeks, consider a referral for a Long-term

CVC. The femoral site should be avoided whenever possible due to the high risk of infection,

thrombosis, and arterial cannulation and is relatively contraindicated as a route for parenteral nutrition.

Femoral CVCs inserted under emergency circumstances should be re-sited to another CVC site within

48 hours of insertion. (O'Grady, et al., 2011) (Pittiruti, Hamilton, Biffi, MacFie, & Pertkiewicz, 2009) (Safer

Healthcare Now, 2012) (Sydney South West Area Health Service, 2007) (Wheeler, Wong, & Shanley, 2007)

Note: Percutaneous Sheath Introducers are only for use in Critical Care Areas.

Whether or not patients with short-term CVCs are appropriate for admission at sites without

24/7 Internal Medicine coverage is a site-based decision taking into consideration patient

safety, staff competency, and patient flow.

Long-Term CVC – A CVC that stays insitu for months to years. Includes Implantable Venous Access

Devices (IVADs), Peripherally Inserted Central Catheters (PICCs), and Tunneled CVCs.

1) Implanted Venous Access Device (IVAD) – [also known as a “port”] A catheter that is

surgically placed into a vessel, body cavity, or organ and is attached to a reservoir or “port”

located under the skin. (Infusion Nurses Society, 2016)

2) Peripherally Inserted Central Catheter (PICC) – A central venous catheter inserted by a

physician or an RN with advanced training and established competency, into an extremity,

typically in the cephalic, basilic or brachial veins of the upper arm. (Infusion Nurses Society, 2016)

3) Tunneled CVC – A long-term CVC whose proximal end is tunneled subcutaneously from the

insertion site and brought out through the skin at an exit site. (Infusion Nurses Society, 2016)

Note: Hemodialysis catheters may be Short-term and temporary or Tunneled and permanent

and may only be accessed by a Renal Nurse. [Exception: In situations that require emergent

or code blue interventions Registered Nurses who work in Critical Care settings (i.e. ER, CCU

and ICU) and have undergone the required education and competency assessment may

access the hemodialysis catheters.]

The type of CVC inserted depends on the:

Type of therapy to be administered

Length of therapy (i.e. Short term or Long term)

Complex or unusual vascular anatomy

Previous devices and complications

Clinical diagnosis and assessment

Clinical situation

Care setting

Patient/family preference

What alternatives are there?

Always advocate for Best Practice!

Site selection includes an assessment of the patient’s condition, age, diagnosis, comorbidities, condition

of the vasculature at the insertion site and proximal to the intended insertion site, condition of skin at

intended insertion site, history of previous venipunctures and access devices, type and duration of

infusion therapy, and patient preference. (Infusion Nurses Society, 2016)

A device with the smallest gauge and least number of lumens needed in order to infuse the prescribed

therapy, length of treatment, duration of dwell, vascular integrity, patient preference, and patient

ability and resources to care for the device should be inserted in an effort to reduce central line-

associated bloodstream infections (CLA-BSIs). (Infusion Nurses Society, 2016) (Safer Healthcare Now, 2012)

Devices inserted for patients in the Residential setting should be single lumen, close-ended, with a

distal valve whenever possible.

When selecting a CVC type, consideration should be given as to whether the device will be used for

high-pressure injection and a suitable device chosen for this purpose. (Infusion Nurses Society, 2016)

A physician’s order is not required to access a CVC, including IVADs.

Reassess the continued need for the CVC daily. Obtain a physician’s order is required to remove the

CVC or provide alternate route for therapy if no longer needed. (Center for Disease Control and Prevention,

2011) (Safer Healthcare Now, 2012)

11

Central Venous Catheters: Single Lumen vs. Multi-lumen Single, double and triple lumen catheters are available in most catheter types

Each lumen must be treated as a separate catheter

Incompatible medications can be infused simultaneously via separate lumens

Exit ports are approximately 2cms apart on the short-term catheter

Central Venous Catheters: Open-ended or Closed-ended Open–ended

The catheter is open at the distal tip

The catheter requires clamping before entry into the system

Clamps are usually built into the catheter

Requires periodic flushing (see Pg. 66)

Any type of CVC can be open-ended

Closed-ended

Valves may be placed distally (at the tip) or proximally (at the hub).

Clamps are not required or built into the catheter as the valve is closed except during infusion

or aspiration.

May be present on Tunneled Catheters, Implanted Ports and PICCs, but NOT Short-term CVCs.

How the negative pressure works with a valved CVC

Valves may be placed distally (at the tip) or proximally (at the hub).

When negative pressure (suction) is applied, the valve opens inward and blood flows into the

syringe.

When positive pressure is applied (fluid infusion or flush) the valve opens outward and fluid

enters the bloodstream.

The valve works when pressure is applied to it. With no pressure the valve remains closed.

When TPN is being infused a lumen MUST be dedicated and labeled for this

use. It is discouraged to administer anything else via that lumen due to

increased incidence of occlusions and infections associated with this practice.

(In a triple lumen catheter, the Medial lumen is typically used)

Short-Term CVCs

A short-term CVC is inserted directly into a large central vein through the skin. These catheters may

be single or multi lumen. Some are sutured in place at the insertion site.

Examples of Short-Term Catheters:

Multi-lumen short-term CVC

Percutaneous introducer

Temporary hemodialysis catheter

Triple lumen short-term CVC

Short term CVCs may be inserted on the Nursing Unit, in

Medical Imaging under fluoroscopy, in the Operating Room, or

Emergency. As a Nurse, you may be asked to assist the

Physician with insertion.

19

Hemodialysis Catheters A hemodialysis catheter (HD line) is a type of Central Venous Catheter used for patients requiring

hemodialysis. The lumens of these catheters are larger allowing for large volumes of blood to be

processed and returned to the patient.

The Renal Program has specific policies and procedures related to these catheters.

HD lines may be accessed by Critical Care Nurses in a Code/ Trauma situation or with

Continuous Renal Replacement Therapy (CRRT).

HD lines are central venous catheters/ Maintain aseptic technique as they are the

patient’s life lines.

Catheter lumens must never be left unattended when open to air.

If there are problems with withdrawing from a lumen do not push locking agent or clot into the

patient.

Once patient stabilizes, plan for use of an alternative access.

The HD line can be used for:

o blood samples

o infusing a medication

o IV infusion

Procedure:

Place patient supine

Create a sterile field/ Don sterile

gloves/mask

Ensure both clamps closed

Scrub the Tego™ connector hub

with alcohol swab and leave to dry

Attach a 10 mL luer syringe,

unclamp and withdraw 5 mL locking

agent, and discard.

Using a second 10 mL syringe,

withdraw and instill blood 2-3 times

(ensures locking agent is cleared)

Flush line with the NS 0.9% 10 mL pre-filled syringe for a total of 20 mL per lumen.

Infusing Medication/ IV infusion

Clamp. Discard syringe. Attach solution tubing

Blood samples

Withdraw 10ml discard from the lumen, clamp and discard. Attach a Vacutainer™ or syringe,

unclamp and take blood samples. Re-clamp. After use flush catheter with 20ml NS 0.9%.

Once you are finished, run an IV 0.9% NS solution at 20 ml/hr.

Notify the Renal Unit that the dialysis line has been accessed.

***A Renal Nurse must flush and re-cap the catheter after the dialysis line has

been accessed.

Nursing Care: Pre/Post Insertion of Short-Term CVCs

Key Points to Remember:

Pre-Insertion:

Prior to insertion ensure the patient/family understands the procedure, its benefits and what might be

expected of the patient during and after insertion (Physician responsibility)

Assess patient’s vital signs and document.

Perform a respiratory assessment including breathing patterns, depth, symmetry, and sounds

Place patient in Trendelenberg position to dilate the veins and reduce the risk of air embolism if tolerated.

Some patients are unable to tolerate this position. When this occurs follow the Physician’s direction.

Use of maximum barrier precautions:

- The patient is covered from head to toe with a sterile drape with a small opening for the insertion site (to

observe/monitor the patient’s head area, consider placing a mayo stand under the drape in this area).

- The inserting practitioner must remove jewellery, wear eye protection, hand wash to remove visible dirt

(soap and water or 2% Chlorhexidine), subsequent hand washing before and after palpating catheter

insertion site (alcohol gel is sufficient), and use a surgical cap (bouffant cap), mask, sterile gown, and sterile

gloves.

- The assisting practitioner must hand wash and use a surgical cap (bouffant cap), mask, sterile gown, and

sterile gloves.

- Other personnel, such as those without direct contact, must wear a mask.

Post-insertion

o Order a portable chest x-ray for Physician to confirm correct placement of line

o NOTE: Do not use CVC until confirmation of placement received by Radiologist or Physician

unless condition warrants need for immediate infusion of large volume of fluid.

o FEMORAL SITE: If a Short-term CVC is inserted into a femoral site – no chest x-ray required. To

confirm correct placement in vein, draw blood gas from the femoral CVC and send sample to

Lab to ensure the results are a venous sample (Venous Blood Gases). In Critical Care areas,

transduce the femoral CVC and ensure you have an appropriate CVP waveform.

o Ensure that all lumens are flushed with 2 x 10 mL of NS pre-filled syringes immediately after insertion.

o Monitor patient vital signs every 30 min x 2

21

Peripherally Inserted Central Catheter (PICC)

Peripherally Inserted Central Catheter (PICC) – A central venous catheter inserted by a physician or an

RN with advanced training and established competency, into an extremity, typically in the cephalic,

basilic or brachial veins of the upper arm. (Infusion Nurses Society, 2016)

Venous access is obtained by puncturing the brachial, cephalic, or basilic vein just above the

antecubital fossa.

The catheters are approximately 40-60 cm long, but are usually individually sized upon insertion.

PICCs are usually chosen for patients requiring IV therapy for more than six days and up to one year,

although a PICC may stay in longer than a year as long as it is still required, functional, and not a

source of sepsis.

TUNNELED

CATHETERS


32

Tunneled Catheters

Tunneled CVC – A long-term CVC whose proximal end is tunneled subcutaneously from the insertion

site and brought out through the skin at an exit site. (Infusion Nurses Society, 2016)

Most tunneled catheters have one or two cuffs, one of which is a dacron cuff on the tunneled

portion of the catheter. and sit 3 - 5 inches above the skin exit site. The cuffs facilitate anchoring of

the catheter through granulation with the tissue and acts as a barrier to infection.

Tunneled catheters may be single, double, or triple lumen.

Examples of Tunneled Catheters are Hickmans®, Broviac® and permanent hemodialysis catheters

(e.g. Perm-Cath®, Hemosplit®, or Equistream®).

Nursing Care: Pre/Post Insertion of Tunneled Catheters Tunneled catheters may be inserted in the Operating Room under a local anaesthetic or in Radiology

under fluoroscopy.

The Nurse’s role in the insertion of a tunneled catheter involves pre-insertion teaching, assessment,

and post-operative site care.

PRE-INSERTION

Ensure patient/family understands reasons for insertion, benefits and risk of procedure.

If possible, provide an opportunity for the patient to see pictures, and handle a demo catheter.

Discuss feelings about potential body image changes (external device).

Perform baseline vital sign assessment.

INSERTION PROCEDURE

This procedure is performed in the Operating Room or Interventional Radiology under sterile

technique

The patient is placed in Trendelenberg position to dilate the veins and reduce the risk of air

embolism

The surgeon accesses the subclavian or internal jugular vein using a percutaneous approach and

inserts the central venous catheter over a guide wire. Once the catheter is placed in the

appropriate vein and the guide wire has been removed, the surgeon selects the exit site. The

surgeon then tunnels the catheter subcutaneously away from the insertion site. Catheters are

typically tunneled for several inches (4-6”) from the location where they enter the vein and usually

exit the body midway between the nipple and the sternum.

o Observe for the occurrence of cardiac dysrhythmias

Q1H:


Sutures are usually removed from the entrance site after seven to ten days, exit site after 14

days, or as per Physician’s Order.

DRESSING: Newly inserted tunneled CVCs have 2 insertion sites. The upper insertion site will have

sutures and needs to have a TSM securement dressing applied until it is well-healed. Sutures are

removed may be removed when the upper and lower incisions are well-healed (usually 7-10 days). The

lower insertion site which the CVC comes out of needs to have a TSM securement dressing to keep the

line from migrating until the insertion site is well-healed and the skin growth into the Dacron cuff holds

it firmly insitu (i.e. 4 – 6 weeks). If the insertion site shows signs of infection (e.g. redness, warm to

touch, purulent discharge, etc.) consult with a physician.

Tunneled CVCs can be left open to the air (with no dressing) after the insertion sites are well healed in

Outpatient and Community settings. (Center for Disease Control and Prevention, 2011) (Olsen, Hanson, Gilpin,

& Heffner, 2004)

Access

Device

(IVAD)


38

Implantable Venous Access Device (IVAD)

IVADs are long-term (months to years) single or dual

chamber “port” surgically implanted in the subcutaneous

tissue, usually in the upper chest.

Each chamber must be managed as a separate lumen in

IVADs with more than 1 septum.

A non-coring point needle is required to access the device.

(see Figure 15)

When de-accessing an IVAD, a 5 mL of heparin 10 units/mL (dose

to be administered = 30 to 50 units) pre-filled syringe is used.

The surgical technique to place an IVAD is similar to that used

to place a tunneled catheter. This procedure is done in the Operating Room or Interventional

Radiology.

IVAD Components

Portal body - May be stainless steel, titanium, or plastic. May be single or double port.

Septum - Self sealing silicone septum which may stay in as long as the device is required, functional,

and is not a source of sepsis.

Reservoir - Inside the port. Volume (of reservoir) is dependant on the size of the port and ranges from

0.2-1.5mL.

Catheter - Tip in superior vena cava. Radiopaque, may be open-ended or close-ended (valved)

Nursing Care: Pre/Post Insertion Pre-Insertion

The nurse’s role in pre-insertion care includes patient education:

Provide information about the surgical insertion of an IVAD to the patient and family. This is a

shared responsibility between the Physician and the RN.

Pamphlets, videos and/or demo catheters may be available at some sites for patient teaching.

Female patients are sent with their bras to the OR/Medical Imaging to aid the surgeon with site

selection.

Advise the patient to carry identification of the port model and composition with them at all

times. The implantable ports can cause minor distortion of the MRI and other x-ray procedures.

Insertion

IVADs are inserted in the OR/MI under a local anesthetic and sterile technique.

A cut down method is used and the catheter is introduced through a venotomy into the subclavian

or internal jugular vein.

The catheter is then positioned with the distal end positioned at the junction of the superior vena

cava and the right atrium.

The portal body is placed over a bony prominence (e.g. ribcage), to ensure easy palpation.

Appropriate site selection is essential.

Once the site is selected, the portal body may be sutured to the fascia on all 4 sides with non-

absorbable sutures to prevent it from twisting or moving. Most are now placed in a small

subcutaneous pocket that does not require suturing.

The port is flushed in the OR/MI. First access usually occurs about one week post-insertion.

The entire procedure takes 30-60 minutes.

Q1H:


The incision dressing may be removed when there is no evidence of drainage (unless

otherwise directed by physician)

Once healed if accessed, a transparent dressing is applied to the site and then the IVAD is

treated as any other CVC. When not accessed, no dressing is required.

Observe and document site condition including:

Wound hematoma, swelling, infection, device rotation and skin necrosis

Slight edema and tenderness around the port implantation site is normal for the first few

days post operatively and does not prevent use unless it is excessive

Most Physicians prefer to wait a few days before accessing, although this is not always

possible if no other access routes are available

“Twiddler’s Syndrome” occurs when a port is dislodged within the subcutaneous

pocket because of trauma to the site or manipulation (twiddling) of the port by the

patient. When this occurs, the port is noted to move easily under the skin. Resistance

may also be noted when attempting to infuse and swelling may occur at the site. If this

occurs, stop using the IVAD and notify the Physician to re-stabilize or re-insert the IVAD.

Power-Injection

Capable CVCs

44

Power-injection Capable CVCs

Pressure-injection capable CVCs are designed to withstand the high pressures created by pressure-

injectors used to administer contract dye in Medical Imaging. CVCs designed for high-pressure injection

must withstand up to 300psi and be clearly labelled as such. (Infusion Nurses Society, 2016)

All CVCs also come in a “power” version – PURPLE often denotes Power injection-capable, but all

vendors will denote power usage on the lumen.

Figure 19 – Image courtesy of Bard® Figure 20 – Image courtesy of Teleflex®

One or more lumens may be power injectable. Imaging may request the RN check the power-injection

capable CVC for patency prior to procedure. This involves easy aspiration of blood and easy flushing.

The RN must verify if an IVAD is power-injection capable before use. This must be confirmed by either

a radiopaque identifier of symbols on the port are visible under X-ray, fluoroscopy or other appropriate

imaging technology or a minimum of two of the following:

i. Patient implant record.

ii. Patient identification card, bracelet or

key chain received when the port was

implanted.

iii. Palpation of the port to identify a

triangular arrangement of three

palpation bumps (not available on all

brands).

Power-injection capable IVADs must only be accessed with a power-injection capable non-

coring needle when required for power-injection.


*** Remember to flush all lumens (including ones with a continuous IV) with 2 x 10 mL pre-

filled NS syringe after IV contrast to prevent occlusions.

COMPLICATIONS ASSOCIATED WITH CENTRAL VENOUS CATHETERS

Infection

Central Line Associated Bloodstream Infections (CLA-BSI) are a preventable nosocomial infection and

adverse event. (Stevens & Schulman, 2012) These infections increase hospital length of stay and facility

costs.

Central Line Associated Bloodstream Infection (CLA-BSI) – This term is specific to CVC

associated bloodstream infections. A CLA-BSI is a bacteremia or fungemia in a patient with a CVC

and no apparent source for the bloodstream infection other than the CVC. There must be at least one

positive blood culture (obtained from a peripheral vein) in addition to the clinical manifestations of

infection (i.e. fever, chills, and/or hypotension) AND had a CVC in use anytime during the 48-hour

period before development of the BSI.

A definitive diagnosis of CLA-BSI requires that the same organism grow from at least 1 percutaneous

blood culture and from a culture of the CVC tip, OR that 2 types of blood samples be drawn (one from

each CVC lumen and the other from a peripheral vein) that, when cultured, meet CLA-BSI criteria for

quantitative blood cultures. Central Line Associated Bloodstream Infections (CLA-BSI) are common,

costly, and potentially lethal. Clinical Practice Guidelines and interventions aimed at decreasing the

infection rate are needed to reduce the mortality, morbidity, and increased patient length of stay, and

increased costs of this hospital-acquired infection. (Center for Disease Control and Prevention, 2011)

(Chittick, et al., 2013) (Chopra, O'Horo, Rogers, Maki, & Safdar, 2013) (Fraser Health Authority, 2009) (Infusion

Nurses Society, 2016) (Mermal, et al., 2009) (O'Grady, et al., 2011) (Safer Healthcare Now, 2012) (Provonost, et

al., 2006)

Infective organisms may access the vascular access device surface by either:

- Invasion of the percutaneous tract

- Contamination of the catheter hub

- Seeding from a remote source of localized infection

(Association for Professionals in Infection Control and Epidemiology, 2009)

Increased CLA-BSI rates in adults are associated with CVCs placed in the jugular and femoral vein

(Center for Disease Control and Prevention, 2011) (Doellman, 2011) (Safer Healthcare Now, 2012) and PICCS in

an inpatient setting (Chopra, O'Horo, Rogers, Maki, & Safdar, 2013).

The nurse and/or IV Therapy Practitioner should assess patients for suspected infusion related and CLA-

BSIs and document signs and symptoms, interventions implemented and patient response to treatment

in the patient’s permanent health record and the Patient Safety Learning System (PSLS). (Infusion

Nurses Society, 2016)

Signs and symptoms of CLA-BSI include:

- Erythema, edema, induration, or drainage at the vascular device insertion site

- Elevated body temperature

http://fhpulse/quality_and_patient_safety/patient_safety_and_learning_system/Pages/Default.aspx

47

Purulent drainage from the catheter-skin junction of a CVC should be collected using the Levine

Technique (cleanse site with normal saline prior to collecting swab for culture and twirl the end of the

cotton-tipped applicator on a 1-cm2 area of the wound bed with enough pressure to cause minimal

bleeding). Rationale: Obtaining the culture from properly cleaned and prepared tissue avoids obtaining

only a culture of surface contamination. (Spear, 2014)

Routine culturing of all CVC tips upon removal is not recommended. Catheter colonization may be

detected, but does not indicate the presence of a bloodstream infection. (Infusion Nurses Society, 2016)

Immediate removal of a functioning CVC is not recommended solely based on temperature elevation.

Clinical findings, such as temperature elevation with or without chills or inflammation and purulence at

the insertion site, are unreliable indicators of bloodstream infection. (Infusion Nurses Society, 2016)

Prior to insertion of a new CVC in a patient with documented CLA-BSI (i.e. positive cultures), it is

recommended the patient receive treatment for the CLA-BSI for 48-72 hours. A negative blood culture

is recommended before a new CVAD is inserted. Rationale: If a new CVC is placed with a bacteremia

present, the device could become seeded and result in continuing infection. Consideration should be

given to the risk versus benefit to the patient when deciding to replace the CVC prior to obtaining

negative cultures. (Daneman, Downing, & Zagorski, 2012)

CVC salvage (avoiding removal of CVC in presence of infection) should be a collaborative decision with

the physician, nurse, and patient based on:

a) The type of CVC (inserted vs surgically implanted)

b) Difficulty with insertion

c) Presence of bleeding disorders

d) CLA-BSI infecting organisms confirmed by at least 2 blood cultures

e) The presence of other complicating conditions including, but not limited to, severe sepsis,

suppurative thrombophlebitis, endocarditis, or the presence of vascular hardware, such as a

pacemaker or implanted defibrillator.

Infection of a subcutaneous tunnel or IVAD pocket requires removal of the CVC; however,

uncomplicated exit-site infection without systemic infection, positive blood cultures, or purulence may

be treated with topical antimicrobial ointment as indicated by culture and sensitivity results. If an IVAD

is removed for suspected infection, the port body should be sent for culture of the reservoir contents as

well as the catheter tip. (Infusion Nurses Society, 2016)

Implementations of “Bundles” are associated with decreased infection rates. Bundles are a group of

evidence-based interventions that, when implemented together, result in better outcomes than when

implemented individually. Components of these bundles may include (but are not limited to):

a) Hand hygiene

b) Maximal barrier precautions during CVC insertion

c) Chlorhexidine skin asepsis

d) Optimal catheter type and site selection

e) Daily review of CVC necessity

f) Aseptic lumen access

g) Routine catheter and tubing site care

(Center for Disease Control and Prevention, 2011) (Pennsylvavia Patient Safety Authority, 2007) (Royer,


48

Air Embolism

Air embolism is the presence of air in the vascular system. (Infusion Nurses Society, 2016) A venous air

embolism occurs when air is introduced into the venous system and travels to the right ventricle and/or

pulmonary circulation. An arterial air embolism results from air entry into the arterial system and can

produce ischemia of and organ with poor collateral circulation. (Broadhurst, 2013, p. 17) Air embolism is

reported to occur more frequently during catheter removal than during insertion. (Truscott, 2013)

The minimum amount of air that is lethal to humans is not known, however, the risks from smaller

amounts increase with a device closer to the central vasculature (CVC) or with pediatric and neonatal

patients, particularly in presence of a patent foramen ovale. (Cook, 2013)

The introduction of microbubbles into the vascular system is also related to the development of an air

embolism and may go unnoticed. Cardiopulmonary bypass, hemodialysis, mechanical heart valves,

major surgeries, warming of cold infusates, and high IV infusion flow rates during trauma resuscitation

can produce large amounts of microbubbles. (Broadhurst, 2013) (Cook, 2013)

Interventions to prevent air embolism include:

1. Minimize CVC manipulations.

2. Remove all air from syringes, IV administration sets, needleless connectors, stopcocks, and all

other devices added to the CVC.

3. Trace all IV lines from the catheter hub to the IV fluid container to prevent misconnections.

4. Remove air bubbles detected during an IV infusion. Infrequent tiny pinhead bubbles, even

though not desirable, can be left but should be monitored.

5. Never use scissors near a CVC to prevent accidental severing of the catheter.

6. Carefully fill and prime IV administration sets and filters and ensure vented tubing in clamped

off before the container is completely empty.

7. Use IV infusion pumps with air sensing technology for IV fluid and medication infusions.

8. Place patient in trendelenberg position during CVC insertion at axillo-subclavian or jugular sites.

9. During CVC insertion stop ventilation during insertion of the needle and increase right atrial

pressure during tunneling of the catheter

10.Have patient perform Valsalva maneuver during insertion of dilator unless they have a condition

which may contradict it (e.g. aortic stenosis, recent MI, glaucoma, and retinopathy).

11.Ensure a catheter clamp is present and clamped before changing administration sets or

needleless connectors on open-ended CVCs.

12.During CVC removal, ensure the catheter exit site is lower than the height of the patient’s

heart.

13.Apply a sterile occlusive petroleum based dressing when removing a CVC and cover that with a

TSM dressing. Leave dressing in place for at least 24 hours.

14.Instruct the patient to lie flat for 30 minutes post CVC removal.

15.Instruct patients and caregivers to not disconnect and reconnect any IV administration sets or

connectors from the catheter hub to properly prime tubing, to check connections frequently,

how to prevent displacement/disconnection, and actions to take in case of CVC displacement or

damage. (Broadhurst, 2013) (Cook, 2013) (Infusion Nurses Society, 2016)

49

Risks for air embolism include:

1. Failure to occlude the needle hub and/or catheter during insertion or removal

2. An improperly primed IV administration set

3. An incorrect technique when administering drugs via the IV route

4. Inadvertent infusions of air

5. An accidental disconnection at the catheter hub, connector, or IV administration set

6. A stopcock placed in the wrong position

7. A ruptured catheter

8. Poor technique during cap changes

9. Poor technique via the track from the removal of a CVC

10.The use of vented IV administration sets

11.IV fluid infusions that are completed or rapid infusion through an air-filled drip chamber with an

IV administration set that is unclamped

12.Passive air entry via a CVC during the inspiratory phase of spontaneous respiratory

Sign and symptoms of air embolism:

1. Sudden onset of dyspnea

2. Continued coughing

3. Breathlessness

4. Agitation or irritability, often expressed as a feeling of impending doom

5. Shoulder and chest pain

6. Lightheadedness

7. Hypotension

8. Jugular venous distention

9. Tachyarrhythmias

10.Wheezing

11.Tachypnea

12.Altered mental status

13.Symptoms that emulate stroke including altered speech, changes in facial appearance,

numbness and paralysis (Cook, 2013) (Infusion Nurses Society, 2016)

Diagnosis may not be straightforward but prompt diagnosis and treatment will decrease potential

mortality and morbidity. Radiological techniques including transthoracic echocardiography and

precordial ultrasonography have been used to detect air embolisms. (Cook, 2013)

Treatment should begin immediately even if an air embolism is only suspected to prevent further air

from entering the vasculature:

1. Close, fold, or clamp the existing catheter to occlude entry of passive air.

2. Occlude the puncture site of a catheter that had been removed.

3. Place the patient in Trendelenberg left lateral decubitus position (left side, head flat, feet up,

right side uppermost) if not contraindicated by other conditions such as increased intracranial

pressure or respiratory illness. The goal of this positioning is to trap the air in the lower portion

of the right ventricle and prevent it from travelling to the pulmonary arteries.

4. Administer oxygen at 100%

5. If possible, attempt to aspirate air from catheter.

6. Monitor vital signs.

7. Notify physician.

(Broadhurst, 2013) (Cook, 2013) (Infusion Nurses Society, 2016) (Wilkins & Unverdorben, 2012)

Catheter Embolism

Catheter embolism is the result of catheter damage or rupture, resulting in the breaking off of a portion

of the CVC into the bloodstream. (Canadian Vascular Access Association, 2013) See also CVC Occlusion

Management Algorithm.

The most frequent causes for catheter embolism are pinch-off syndrome, damage during catheter

exchange, separation of the catheter from an implanted port body, and fracture of a distal portion of an

IVAD. (Infusion Nurses Society, 2016)

Interventions to prevent catheter embolism include (Infusion Nurses Society, 2016):

1. Do not withdraw a catheter through a needle during insertion.

2. Never use vascular access devices for power-injection that are not rated for this purpose.

3. The size of the flush syringe should be in accordance with the type of vascular access device

and its intended use.

4. Be aware of the early signs of pinch-off syndrome in subclavian CVC insertion sites (when the

subclavian vein is compressed between the clavicle and the first rib). Up to 40% of these cases

may develop catheter fragmentation and embolization of catheter fragments into the pulmonary

artery or heart. Pinch-off syndrome may be asymptomatic or may present as the intermittent or

constant inability to aspirate blood from a CVC. Occasionally it may present as chest pain or

arrhythmias during infusion procedures or if the patient has to maintain an unnatural position

(e.g. arm raised) in order to infuse a solution or medication. To identify pinch-off syndrome, a

specific CXR is required (with patient arms kept down at sides). (Canadian Vascular Access

Association, 2013) (Infusion Nurses Society, 2016)

Catheter dysfunction, such as the inability to aspirate blood or fluid with localized pain and/or

subcutaneous swelling, may be a precursor to catheter embolism. Leaking at the catheter insertion may

indicate catheter rupture. CVCs which exhibit these signs should be evaluated further for integrity

before use (e.g. CXR for fragmentation or pinch-off syndrome). (Infusion Nurses Society, 2016)

Catheter embolism should be suspected when the patient exhibits symptoms such as palpitations,

arrhythmias, dyspnea, cough, or thoracic pain not associated with patient’s diagnosis or comorbidities.

(Infusion Nurses Society, 2016)

Upon removal, inspect all catheters for damage and possible fragmentation. When vascular access

device removal is difficult or if damage to the catheter is seen:

1. Carefully assess the patient for signs and symptoms of catheter fragmentation and;

2. Save catheter and report via PSLS and BCCSS Product Concern Form.

Debris in IV solution (some may require filter -refer to PDTM)

Debris caused by incompletely dissolved, reconstituted drugs

Unfiltered blood or plasma

Prevention:

NEVER irrigate the catheter if the IV is not flowing

Use in-line filters where applicable (see PDTM)

Thoroughly inspect medication and solution containers for particulate matter prior to use

Signs and Symptoms:

Apprehension

Pleuritic discomfort

Dyspnea, tachypnea

Cyanosis

Cough, unexplained

Hemoptysis

Diaphoresis

Tachycardia

Catheter-Related Thrombosis (CRT) or Catheter-Associated Venous Thrombus

This term refers to a thrombus that has attached to the CVC and has also adhered to the vessel wall.

CRT is associated with CLA-BSI. CRT increases the risk and incidence of CLA-BSI. Conversely, CLA-BSI

also increases the risk and incidence of CRT. (Canadian Vascular Access Association, 2013)

Risk factors for CRT include:

1. Sub-optimal CVC tip placement

2. Difficult, previous, or traumatic insertions

3. PICCs with multiple lumens or larger gauges or inserted in the ACF

4. Children and adults over 60 years of age

5. Chronic illnesses such as lupus, irritable bowel syndrome, or end-stage renal failure

6. History of previous DVT (Yacopetti, 2008)

Signs and symptoms are related to the obstruction of venous blood flow and include:

1. Pain in the extremity, shoulder, neck, or chest

2. Edema in the extremity, shoulder, neck, or chest

3. Engorged peripheral veins in the shoulder, neck, or chest wall (Infusion Nurses Society, 2016)

(Yacopetti, 2008)

CVC flushing and locking procedures have no effect on CRT as the solutions and technique are directed

at the internal lumen of the CVC rather than the vein lumen. (Infusion Nurses Society, 2016)

Usual management of CRT includes thrombolysis and systemic anti-coagulation with or without CVC

removal. Consider removal of CVC with caution as this may be their only vascular access and systemic

anti-coagulation increases their risk for bleeding.

CVCs should be removed in cases of:

1. Infected thrombus;

2. Malposition of the tip (radiologic reposition of the tip often fails, as a consequence of the

inability to reach it inside the thrombus); or

3. Irreversible occlusion of the lumen.

(Campisi, Biffi, & Pittiruti, 2007) (Infusion Nurses Society, 2016) (Yacopetti, 2008)

Prophylactic anti-coagulation is controversial and compliance has been shown to be poor. Focus should

therefore be on prevention of CRT:

1. Insertion of longer-term CVCs in applicable patients earlier in their course of treatment

2. Use of advanced technology on insertion (e.g. ultrasound, modified Seldinger technique, tip

placement technology)

3. Right-sided placement is preferred as the required CVC length is shorter and more likely to lie

parallel in the vessel

Phlebitis and Thrombophlebitis

Phlebitis is inflammation of the wall of a vein.

Thrombophlebitis is when a blood clot in the vein causes

the inflammation.

These conditions are characterized by pain, erythema,

swelling, and palpable thrombosis of the cannulated vein.

Risk factors for phlebitis include:

- Patients who are female

- Patients with poor-quality peripheral veins

- Insertion in the lower extremity, antecubital fossa,

and points of flexion

- The presence of underlying medical conditions

including cancer and immunodeficiency

- Insertion in an emergency

There are 3 major types of phlebitis: mechanical,

bacterial, and chemical:

Inserting a vascular access device causes mechanical

disruption to the skin, the body’s first line of defense

against infection. Movement of the cannula in the site also

causes mechanical injury to the vein, as does using a

catheter too large for the site.

When the skin is breached, patients are at risk for bacterial

infection. Hand hygiene and cleansing the insertion site

thoroughly before insertion and applying a dressing after

are the major steps to prevent bacterial infection.

Chemical phlebitis can be related to the tonicity of the

fluid, the number and dosage of medications, the pH of the

medications, or wet skin. In particular, 5% dextrose in

water is isotonic in the bag but hypotonic in the body after

the dextrose is infused and metabolized. Hypertonic fluids

pull fluids from the endothelium, causing the cells to shrink

and making them vulnerable to infiltrations and phlebitis. C

(Washington & Barrett, 2012) Chemical irritation also happens

when the skin is not allowed to dry after cleaning and before insertion of the catheter.

Phlebitis may occur at rates as high as 50% or even as high as 75% in patients with infectious

diseases; however, the incidence rate in patients who do not have diabetes, burns, or a need for urgent

catheter insertion is approximately 20%. This inflammation may occur while the catheter is in place and

up to 96 hours after removal. The residual occurrence of phlebitis may still be a problem to the patient

as long as 5 months after the incident.

All vascular access sites should be routinely assessed for the signs and symptoms of phlebitis.

(Dychter, Gold, Carson, & Haller, 2012) (Groll, Davies, MacDonald, Nelson, & Virani, 2010) (Hadaway, Short

Peripheral Catheters and Infection, 2012) (Infusion Nurses Society, 2016) (Tripathi, Kaushik, & Singh, 2008)

(Washington & Barrett, 2012)

Infiltration and Extravasation

All vascular access sites should be routinely assessed for the signs and symptoms of infiltration and

extravasation.

Infiltration is defined as the inadvertent leakage of a non-vesicant solution into surrounding tissue.

Extravasation is the inadvertent leakage of a vesicant solution into surrounding tissue.

Extravasation is associated with cytotoxic chemotherapy agents such as doxorubicin, paclitaxel, and

vinca alkaloids, as well as a number of non-cytotoxic drugs, including phenytoin, sodium bicarbonate

(>5%), calcium chloride and gluconate, amphotericin B, acyclovir, ganciclovir, digoxin, diazepam,

potassium (>40 mmol/L), dextrose 50%, cefotaxime, IV contrast media, and mannitol, that can also

cause tissue necrosis. The incidence of infiltration and extravasation is hard to determine because of

limited reporting; however, extravasation injury from cancer chemotherapy is reported to be 11% in

children and 22% in adults. Rates of extravasation with cancer chemotherapy infused through

implanted ports range from 0.3% to 6%. (Dychter, Gold, Carson, & Haller, 2012) (Hadaway, 2007)

Measures to prevent infiltration and extravasation include:

- Selection of an appropriate site for catheter insertion

- Selection of an appropriate size catheter - Use the smallest size catheter needed for the

prescribed therapy

- Use of appropriate fluids depending on vascular access type – Medications/fluids with an

osmolarity of greater than 900, a pH of less than 5 or greater than 9, and vesicants should be

given via a CVC.

- Stabilization of the catheter – Always use a securement device/dressing. Avoid

circumferential taping of a limb.

- Use of proper administration techniques - The patency of the catheter and vein should be

assessed frequently so that infiltration or extravasation can be prevented. Before

administering each dose of medication, the nurse should visually inspect and palpate the site,

checking for vein cording, edema, skin temperature, and tenderness or discomfort. Check for

a positive blood return. Each drug should be diluted in a separate syringe. When dilution is

done either in a syringe or by slow injection through an infusing, compatible IV fluid,

according to the PDTM, the injection can be stopped if the patient complains of any problems.

(Hadaway, 2007)

- More frequent site assessments when administering vesicants:

Every 5 to 10 minutes for patients receiving peripheral intermittent infusions of

vesicants (NOTE: The nurse should advocate for central vascular access administration

of vesicant medications whenever possible. The peripheral infusion of vesicant agents

should be limited to less than 30 to 60 minutes. In addition to visual assessment of the

site, a blood return should be verified every 5 to 10 minutes during the infusion.)


Patients receiving chemotherapeutic vesicants: The RN will remain with the patient, and

will check blood return and assess the IV site every 2 minutes throughout the

procedure. (BC Cancer Agency, 2014)

55

Common signs and symptoms of IV infiltration include:

- Cool skin temperature at the insertion site

- Skin that looks blanched, taut, or stretched or that the patient says feels “tight”

- Discomfort and/or tenderness

- Change in quality and flow of the infusion

- Frequent IV infusion pump downstream occlusion alarms (do not rely on an IV infusion pump

to alert you to an infiltration as this alarm is often a late sign; an IV infusion pump will

exacerbate the problem until the IV infusion pump is stopped) (Pennsylvavia Patient Safety

Authority, 2007)

- Edema/ IV fluid leaking from the insertion site (may be related to a catheter fracture, see

Broken/Damaged CVCs)

(Amjad, Murphy, Nylander-Housholder, & Ranft, 2011) (Dychter, Gold, Carson, & Haller, 2012) (Hadaway,

2007) (Infusion Nurses Society, 2016) (Simona Pop, 2012)

Signs and symptoms of extravasation are the same as those of infiltration but also include

burning/stinging pain, redness followed by blistering, tissue necrosis, and ulceration. Both infiltration

and extravasation can have serious consequences including full-thickness skin loss, compartment

syndrome, and muscle and tendon necrosis. The patient may need surgical intervention resulting in

large scars, experience limited function, or even require amputation. Another long-term effect is

complex regional pain syndrome, a neurologic syndrome requiring long-term pain management. (Amjad,

Murphy, Nylander-Housholder, & Ranft, 2011) (Dychter, Gold, Carson, & Haller, 2012) (Hadaway, 2007) (Infusion

Nurses Society, 2016) (Simona Pop, 2012)

Occlusions (Canadian Vascular Access Association, 2013) See also CVC Occlusion Management Algorithm

Standards - Immediately after a CVC is inserted into a vessel, the coagulation cascade begins.

Thrombus formation may occur within 24 hours of insertion. CVC occlusions can result in interruptions

or delays in therapy, infection, embolism, or loss of vascular access. Proper care, maintenance,

continued assessment, and early recognition of the pending signs of occlusions can improve patient

outcomes and minimize organizational costs. CVCs may remain insitu for as long as the device is

functional and required. Restoration of catheter patency supports the longevity of the device’s lifespan.

CVC replacement costs include cost of the device, supplies, and nursing, clinic, and physician time. The

cost of thrombolysis is markedly less than device replacement, both in terms of patient access to

treatment and safety and well as financial impacts to the healthcare facility. Catheter salvage and

restoring patency (rather than device removal) is the preferred approach to the management of CVC

occlusions. Catheter patency is the ability to easily aspirate blood from a CVC lumen and to easily

infuse or flush fluid through a CVC lumen. Catheter patency can be compromised by any type of

occlusion.

Signs and Symptoms of CVC occlusions:

i. Upon infusion or flushing:

1. Resistance when flushing

2. Sluggish flow

3. Inability to infuse fluids or medications

4. Frequent downstream or patient-side occlusion alarms on IV infusion pump

5. Infiltration, extravasation, swelling, or leaking at the insertion site

ii. Upon aspiration of blood:

1. Inability to withdraw blood

2. Sluggish blood return

56

Types of CVC Occlusions:

i. Thrombotic Occlusions - Thrombotic occlusions are responsible for approximately 58% of all

occlusions. Occlusions develop as fibrin builds on and around the catheter and vessel. In

addition to causing catheter dysfunction, thrombotic occlusions can lead to catheter-related

thrombosis (CRT). (See also Catheter-Related Thrombus)

ii. Chemical Occlusions – Non-thrombotic causes of occlusion account for 42% of all occlusions

and are related to medication or drug precipitate. They can specifically be the result of

precipitate from the mixing of incompatible medications and solutions or lipid residue.

iii. Mechanical Occlusions – Mechanical occlusions are related to internal or external problems

with the CVC. They include CVC or tubing kinks, (see also CVC Measurement and Device

Malposition), a clogged needleless connector or filter, and incorrect placement of a non-coring

needle into an IVAD.

Degree/Type of Occlusion – There are three degrees/types of occlusion:

i. Partial – Decreased ability to infuse fluids/medications into the CVC; resistance with flushing

and aspiration; Sluggish flow through the CVC. Causes: Chemical, Mechanical, or Thrombotic

occlusion.

ii. Withdrawal – Inability to aspirate blood through the CVC, but ability to infuse without any

resistance; Lack of free-flowing blood return. Causes: Mechanical or Thrombotic occlusion.

iii. Complete – Inability to infuse or withdraw blood or fluid into the CVC. Causes: Chemical,

Mechanical, or Thrombotic occlusion.

CVC occlusions should be investigated to identify the type of occlusion for appropriate management as

soon as they are identified. (See also CVC Occlusion Management Algorithm)

Administration of Unblocking Agents - Thrombolytics (alteplase®) can be

administered as per the Parenteral Drug Therapy Manual by any CVC competent

Registered Nurse. Specific RNs designated for this skill will be identified by the Site,

Program, or Sector. The procedure Central Venous Catheter: Unblocking with

Alteplase® can be found on Clinical Skills by Elsevier. Administration of agents to

unblock chemical occlusions (from high pH drugs, low pH drugs, and lipids) in CVCs will

be limited to PICC RNs and as per the Parenteral Drug Therapy Manual.

PREVENTION OF OCCLUSIONS

Prevent occlusions by turbulent flushing before & after use, between

incompatible medications, after blood draws, and regular flushes of lumens not in use

If there is resistance to flushing, lack of free-flowing blood return, or complete inability to infuse

or flush call an RN who has been competency assessed to unblock the CVC (this may vary from

site to site so check your local guideline)

CVC Measurement and Device Malposition

The external segment of all CVCs (except IVADs and Tunneled CVCs) must be measured a minimum of

daily in acute care settings and with each use in community care settings.

If the daily external CVC measurement is altered:

i. Greater than 4 cm out from the baseline insertion length:

- STOP infusion

- Reconfirm placement with CXR and consult with PICC RN or Most Responsible Physician

(MRP) before re-starting infusion

ii. 2 cm in from insertion site:

- STOP infusion

- Consult PICC RN or MRP before re-starting infusion

- A PICC RN or Competency Assessed RN may “withdraw” the CVC back to the original

measurement.

If the CVC migrates greater than 4 cm outwards from the insertion baseline, the CVC must not be used

until placement is confirmed radiographically (e.g. ultrasound, x-ray, or fluoroscopy) by a PICC nurse

or a physician. (Registered Nurses Association of Ontario, 2008)

Secondary CVC malposition, also known as tip migration, may occur at any time during the CVC dwell

time and is related to sporadic changes in intrathoracic pressure (e.g. coughing, vomiting), presence of

CHF, neck or arm movement, positive pressure ventilation, high pressure injection (e.g. contrast

media), or flushing techniques. PICC tip migration is associated with arm adduction and flexion. CVC

dislodgement is caused by arm movement, body posture, lifestyle, and patient manipulation (IVADs

and Twiddler’s Syndrome). (Infusion Nurses Society, 2016)

Do not advance any portion of the CVC that has been in contact with the skin into the insertion site.

Rationale: Skin cannot be rendered sterile. (Infusion Nurses Society, 2016)

Infusions through a malpositioned CVC should be withheld or alternate access established until proper

tip position has been confirmed. (Infusion Nurses Society, 2016)

59

Broken/ Damaged CVCs

The use of a blood pressure cuff on the extremity with a CVC (i.e. PICC) in place is not specifically

stated as a standard. However, based on anatomy and physiology, the pressure resulting from the

application of a tourniquet or blood pressure cuff may result in damage to the catheter and/or vessel

that is accessed. Best practice remains that the blood pressure cuff should be placed distal to the

catheter’s location. A tourniquet can be placed and lab work drawn below a PICC insertion site. (Infusion

Nurses Society, 2013)

Immediately upon discovery of catheter damage, the CVC should be clamped or sealed (e.g. closing an

existing clamp, adding a non-toothed clamp, covering the damaged area with a TSM dressing, folding

the external segment, and securing) between the patient and the damaged area. Rationale: To prevent

air embolism or bleeding from the device. (Infusion Nurses Society, 2016)

Not all CVCs can be repaired. To determine if the patient’s CVC can be repaired, see site specific

algorithms. If the CVC cannot be repaired it should be removed and alternate vascular access

established (if needed). (Gorski, 2007) (Infusion Nurses Society, 2016)

Repairs of a CVC shall only be completed by a PICC RN competency-assessed in CVC repairs. (Gorski,

2007)

CVC damage increases the risk for catheter fracture and embolization, air emboli, bleeding, CVC lumen

occlusion, and CLA-BSI. If CVC repair is possible, it should be performed as soon as possible to reduce

the risk of these complications. (Infusion Nurses Society, 2016)

Causes of device damage should be reported through PSLS and a BCCSS Product Concern Form (in

the case of device failure). Data should be analyzed to identify the root cause(s) including, but not

limited to, device failure, flushing technique, syringe size, and using scissors during a dressing change.

CARE

AND MAINTENANCE OF CENTRAL

VENOUS

CATHETERS

63

Care and Maintenance of Central Venous Catheters

Patient Positioning When caring for open-ended catheters patients should be positioned:

Flat, supine with no pillow for:

o Changing IV tubing or extension tubing

o Repositioning/removing catheter

o Initial capping/flushing

o Insertion

Any position for:

o Blood work using vacutainer method

o Flushing capped lines

o Dressing changes

Closed-ended catheters or IVADs do not require positioning to prevent air-entering catheter. The

relatively long length and small diameter of an open-ended PICC significantly reduces but does not

eliminate the risk of air embolus.

Management of Patients with a CVC Pre-Insertion Assessment:

Vital Signs including BP, HR and RR

Respiratory assessment including: breathing patterns, depth and symmetry of breath sounds

Post-Insertion Assessment and q30 minutes x 2:

Vital signs (as above)

You may apply warm compress to arm above PICC insertion site – QID x 20 minutes for 3

days. This is to prevent mechanical phlebitis.

NO blood pressures or venipunctures to be completed on arm where a PICC has been inserted

Check for signs of and report to Physician:

- Subcutaneous emphysema

- Bleeding

- Air embolus

- Pneumothorax

The two most frequent reasons for loss of central venous access are occlusion and infection.

Therefore, pay particular attention to flushing and catheter care techniques

64




- Ventilator system pressures changes

Cardiac Monitored Patients:

- Cardiac dysrhythmias

Admission assessment, at the beginning of every shift, and q4h check:

Dressing/site - secure, dry and intact.

Condition of site (any inflammation/infection, drainage, edema, bruising, bleeding, subcutaneous

emphysema etc.) - palpate around site.

System check:

- Catheter is secure.

- Condition of the catheter (i.e. no kinks, cracks etc.)

- All connections luer-locked and intact

- Site condition and patency of infusion

Medications and Tubing Electronic infusion pumps must be used for all infusions administered through a CVC in the acute

care setting

All connections must be luer-locked.

IV Tubing changes: See Appendix F

Neutral Displacement Caps Only neutral displacement injection caps are used to cap CVCs

Caps are not needed on lumens when there is a continuous infusion or CVP

monitoring, however, when the CVC is being accessed frequently or

dependent on the setting (i.e. Community), neutral displacement caps may

still be used.

Neutral displacement caps – change q96h and prn in acute and residential

care and q6-7days in community and outpatient clinics

Clamps (built into the CVC) Clamps must be used when accessing and de-accessing an open-ended CVC to prevent air

embolism or blood backflow.

Open-ended catheters are clamped at all times when not in use

Clamps are not used on a valved CVC

A non-toothed or padded forceps must be available at all times in the

event of a break in the catheter lumen

Do not use a sharp edged clamp or hemostat as they can damage the

catheter

Only clamp the reinforced segment of the catheter

65

Flushing Always use 10 mL syringes for flushes for CVC as excessive

pressure (caused by syringes smaller than 10 mL when

flushing and syringes greater than 10 mL when aspirating) can

cause catheter damage

Flushing ensures patency of the catheter

All unused lumens must be flushed at specific intervals

Turbulent flush method (stop/start) should be used. At any

time if unable to flush - DO NOT FORCE. See OCCLUSIONS

Cleansing

Solution at the insertion site:

Use 2% chlorhexidine (CHG) with 70% alcohol cleansing solution in single-use packages. If there is a

contraindication for the use of alcoholic CHG, povidone-iodine or 70% alcohol may also be used.

Rationale: Alcohol provides instant bactericidal action to the skin surface. CHG provides long-acting

anti-microbial action. Single-use packages support infection control practices. (Alexander, Corrigan,

Gorski, Hankins, & Perucca, 2010) (Center for Disease Control and Prevention, 2011) (Hunter & Hunter, 2012)

(Infusion Nurses Society, 2016) (O'Grady, et al., 2011) (Provonost, et al., 2006) (Registered Nurses Association of

Ontario, 2008) (Safer Healthcare Now, 2012)

Allow area to dry completely. Rationale: Solution must be dry for maximum anti-microbial effect. If not

completely dry, CHG in the cleansing solution can react with the dressing adhesive, causing a chemical

burn on the client’s skin. CHG-based cleansing solutions and Iodine-based cleansing solution may take

longer than 2 min to dry completely. (Alexander, Corrigan, Gorski, Hankins, & Perucca, 2010) (Center for

Disease Control and Prevention, 2011) (Infusion Nurses Society, 2016) (O'Grady, et al., 2011) (Provonost, et al.,


Solution at connections:

Use 70% alcohol cleansing solution in single-use packages at needleless connector hubs (includes IV

caps, CVC catheter hubs, and Y-sites) immediately prior to each use. Rationale: While CHG 2% /Alcohol

70% may be used to cleanse the catheter hub, there is insufficient evidence that using CHG for

anything other than skin preparation is beneficial. (Center for Disease Control and Prevention, 2011) (Safer

Healthcare Now, 2012)

Scrub the needleless connector hubs for a minimum of 30 seconds and allow them to dry completely

before use. Rationale: Vigorous cleansing of 15-30 seconds is required for maximum effect. Solution

must be dry for maximum anti-microbial effect. (Center for Disease Control and Prevention, 2011) (Hadaway,

Needleless Connectors: Improving Practice, Reducing Risks, 2011) (Kaler & Chinn, 2007) (Safer Healthcare Now,

2012)

FAILURE TO ALLOW THE SKIN TO DRY COMPLETELY BEFORE APPLYING THE

TRANSPARENT DRESSING MAY CAUSE A CHEMICAL BURN ON THE PATIENT’S SKIN

DUE TO THE CHLORHEXIDINE IN THE CLEANSING SOLUTION. Figures 32 & 33 - Images courtesy of 3M®

67

When cleansing the hub with cap changes, remove old cap, then scrub the CVC hub for a minimum of

30 seconds and allow to dry completely. Rationale: Particulate matter trapped under the old cap is not

removed unless you take off the old cap to access this area, leading to an increased risk of infection.

(Alexander, Corrigan, Gorski, Hankins, & Perucca, 2010) (Center for Disease Control and Prevention, 2011)

(Infusion Nurses Society, 2016) (Safer Healthcare Now, 2012)

Technique for skin preparation:

Use a friction technique in a back-and-forth pattern for at least 30 seconds. Cleanse an area larger than

the intended dressing and allow solution to air-dry completely prior to applying dressing.

Rationale: Friction allows the CHG to penetrate the lower layers of the epidermis, killing a greater

number of skin organisms. (Alexander, Corrigan, Gorski, Hankins, & Perucca, 2010) (Center for Disease Control

and Prevention, 2011) (Infusion Nurses Society, 2016) (O'Grady, et al., 2011) (Provonost, et al., 2006) (Safer

Healthcare Now, 2012)

Securement Use a securement device on all CVCs. The device may be a stand-alone device or integrated into a

dressing specified by the manufacturer to have securement properties. Rationale: Catheter stabilization

shall be used to preserve the integrity of the access device and to prevent catheter migration and loss

of access. (Infusion Nurses Society, 2016)

Sutures/staples/tape should be replaced with a manufactured stabilization dressing and/or device

whenever feasible. Rationale: The use of sutures, staples and tape have been shown to increase the

risk of skin breakdown and infection at the CVC site. (Bishop, et al., 2007) (Infusion Nurses Society, 2016)

Dressings Types of dressings

Transparent semi-permeable membrane (TSM) dressings are recommended as the first choice for CVC

dressings. The dressing used in FH for CVCs already has incorporated material for sensitive skin as a

standard. Rationale: TSM dressings assist in securement and assessment by allowing for continuous

visualization of the CVC site and optimal moisture vapor transfer to prevent skin breakdown from

prolonged dressing use. (Center for Disease Control and Prevention, 2011) (Infusion Nurses Society, 2016)

(Safer Healthcare Now, 2012)

Gauze dressings can be used as a second choice if indicated (i.e. bleeding, drainage, diaphoresis, skin

sensitivity or allergy), but are not preferred.

The use of Chlorhexidine-impregnated dressing with CVCs should be considered as an additional CLA-

BSI prevention measure and for the dressing’s absorptive qualities. (Infusion Nurses Society, 2016)

(Mermal, et al., 2009) (Ho & Liton, 2009) (Perencevich & Pittet, 2009) (Ruschulte, et al., 2009) (Timsit, et al.,

2009) CHG-impregnated dressings shall be applied on all newly inserted CVC sites.

Frequency of dressing changes

When a Chlorhexidine-impregnated dressing is applied on initial insertion of the CVC, it is acceptable to

do the initial dressing change in 6-7 days. A non-Chlorhexidine-impregnated dressing may be used for

subsequent dressing changes. Dressings on newly inserted CVCs should be assessed 24 hrs post CVC

insertion. Rationale: Assess dressings in the first 24 hours for accumulation of blood, fluid or moisture

beneath the dressing. (Bishop, et al., 2007) (Safer Healthcare Now, 2012) Rationale: The risk of

dislodgement outweighs the risk of infection. (Center for Disease Control and Prevention, 2011)

TSM dressings must be changed at least every 6-7 days and gauze-only and gauze+TSM dressings at

least every 48 hrs. Change dressings more frequently if indicated (i.e. if the dressing becomes damp,

loose, soiled, saturated, when the site needs to be assessed, or to coordinate care). Rationale: Gauze

dressings that prevent visualization of the insertion site should be changed routinely every 48 hours

and immediately if the integrity of the dressing is comprised. (Alexander, Corrigan, Gorski, Hankins, &

Perucca, 2010) (Infusion Nurses Society, 2016)

If gauze is used to support the wings of a non-coring needle during IVAD access and it does not cover

the insertion site under the TSM dressing, it can be considered part of the TSM and changed every 7

days.

Newly inserted tunneled CVCs have 2 insertion sites. The upper insertion site will have sutures and

needs to have a TSM securement dressing applied until it is well-healed. Sutures are removed may be

removed when the upper and lower incisions are well-healed (usually 7-10 days). The lower insertion

site which the CVC comes out of needs to have a TSM securement dressing to keep the line from

migrating until the insertion site is well-healed and the skin growth into the Dacron cuff holds it firmly

insitu (i.e. 4 – 6 weeks). If the insertion site shows signs of infection (e.g. redness, warm to touch,

purulent discharge, etc.) consult with a physician.

69

Newly inserted IVADs will have a dressing and sutures in the upper chest wall. Sutures are removed

may be removed when the upper and lower incisions are well-healed (usually 7-10 days). Suture

removal is within the RN Scope of Practice to perform without an order from a physician. (College of

Registered Nurses of British Columbia, 2015) If the insertion site shows signs of infection (e.g. redness,

warm to touch, purulent discharge, etc.) consult with a physician.

Topical anesthetic cream/patches may be used to decrease pain at an IVAD access site. However,

topical anesthetic cream/patches should not be used on the access site of a newly inserted IVAD where

incision glue has been used (instead of stitches), as there has been shown to be a reaction between

topical anesthetic cream/patches and incision glue that may contribute to the development of an

infection.

Dressings should be applied to tunneled CVCs in inpatient and residential settings. Rationale: CVC sites

should be covered due to the increased risk of nosocomial infections in the acute care setting. (Center

for Disease Control and Prevention, 2011)

The dressing on a Hemodialysis Catheter is cared for by the Renal Unit nurses during Hemodialysis.

Exception: Registered Nurses working in a non-Renal clinical area may change a dressing if it is

compromised (i.e. if the dressing becomes damp, loose, or soiled) between hemodialysis treatments or

after renal unit hours in order to protect the site from potential infection. The Renal Unit should be

notified as soon as possible of any new complications with the hemodialysis catheter, such as profuse

bleeding, dislodgement, or fever.

Skin Care All interventions related to IV Therapy, have the potential to affect skin integrity; from the cleansing

solution, to the friction scrub, to the securement device, to the application of the dressing. Catheter

insertion also creates an unavoidable full-thickness wound at the entry site. Cleansing solutions and a

friction scrub disrupt the skin and create shearing forces on the skin. Antimicrobial preparation of the

skin is necessary, but disrupts the natural flora of the skin by design.

Securement devices and dressings can contribute to shearing forces on the skin. Unfortunately, despite

the prevalence of IV Therapy, little research has been done on the effects on the skin.

When erythema is present after application of cleansing solutions, it is generally presumed to be an

allergic reaction. However, two forms of contact dermatitis have been reported in the literature.

Allowing the cleansing solution to dry completely before dressing application and the use of new

dressing products made for sensitive skin will help to alleviate this is a large sector of

the population.

Adhesive trauma is also present, particularly skin stripping and tension blisters. Correct

application and removal techniques for adhesive products are vital to avoid injury to

the skin. Ensure you follow all of the manufacturer’s directions for use.

To prevent damage to the skin, a sterile barrier product shall be applied to the skin after

the cleansing solution has dried completely. If using a CHG-impregnated CVC

dressing, do not apply the barrier film to the area where the CHG pad will contact the

skin.

Figure 35


70

Use of a sterile clear acrylic absorbent dressing product underneath the TSM dressing has been shown

to be effective in managing skin tears without compromising the efficacy of a TSM dressing with

securement properties. See also Clinical Skills by Elsevier for application procedure.

In cases of more severe or complex skin damage, complete a Wound Assessment and consult with your

Wound Care Clinician as required.

(Thayer, 2012)

Blood Sampling

Blood sampling for laboratory testing from a CVC should be considered based on an evaluation

of benefits versus risks. (Infusion Nurses Society, 2016)

Blood must be drawn in a certain order. Refer to the Fraser Health Lab Accessioning Manual for

further information.

The discard method of drawing blood will be used [Exception: Venous Arterial blood

Management Protection (VAMP) system in Critical Care areas]. Rationale: Other methods have

the potential to cause hemolysis and/or re-infuse clots. (Registered Nurses Association of

Ontario, 2008)

Use the largest lumen (usually distal) of multi-lumen CVCs whenever possible. Rationale:

Decreases the risk of a thrombus occluding the lumen. (Registered Nurses Association of

Ontario, 2008)

Have a dedicated lumen for blood draws if able. Rationale: Reduces risk of contaminated sample

due to catheter biofilm, including Parenteral Nutrition. (Alexander, Corrigan, Gorski, Hankins, &

Perucca, 2010) (Edwards Lifesciences, 2002) (Infusion Nurses Society, 2016) (Infusion Nurses

Society, 2011) (Registered Nurses Association of Ontario, 2008)

Stop all infusions prior to blood sampling. For drug levels, it is not recommended to draw the

level from the same lumen being used for the drug infusion, but caution should still be taken

when interpreting results of therapeutic drug levels draw through a CVC. Rationale: Drug levels

may be inaccurate when obtained through the same catheter lumen

used for drug infusion. (Infusion Nurses Society, 2016)

When drawing blood from a CVC with a continuous infusion running

without the use of a connector/ neutral displacement cap, stop the

infusion(s), remove the administration set, and attach the luer lock

Vacutainer® (see Figure 29) directly to the catheter lumen.

Exception: Blood Cultures must be done using syringe method ONLY. See Blood

Cultures.

71

For a capped CVC, luer lock the Vacutainer® directly to the connector/ neutral displacement cap

and then change connector/ neutral displacement cap following the blood draw. However, it is

not recommended to do blood draws through a cap. (Hadaway, Technology of flushing vascular

access devices, 2006) (Infusion Nurses Society, 2016) (Knue, Doellman, Rabin, & Jacobs, 2005)

(Registered Nurses Association of Ontario, 2008)

If the results of coagulation tests are used to monitor anticoagulation treatment or evaluate

coagulopathy, heparinized CVCs should not be used for the blood draw (Frey, 2003). If there is

any doubt as to the accuracy of coagulation studies the sample should be obtained from a

peripheral vein (Bishop, et al., 2007).

Blood Draw discard amount: In all cases, non-additive tubes should be used to collect the discard.

The discard amount when drawing blood is 5 mL. The only exceptions are:

When drawing coagulation studies in adults, the discard amount should be 10 mL. Rationale:

Amount needs to be appropriate to ensure accuracy of lab results, while limited to the minimum

needed to avoid significant blood loss due to frequent sampling Prevents contamination of

samples from tube additive. (Bard Access Systems Inc., 2007) (Edwards Lifesciences, 2002)

(Fraser Health Authority, 2008) (Registered Nurses Association of Ontario, 2008)

No discard is done when drawing blood cultures. (Infusion Nurses Society, 2016)

Blood Draw post-flushing: Draw the blood, change the neutral displacement cap (when one was

present for the blood draw), and flush the CVC with:

Adult - 20 mL NS

Rationale: It is impossible to get all the residual blood out of the connector/ neutral

displacement cap. Residual blood may leads to an increased risk of infection.

Blood Cultures: Peripheral sampling should be done whenever possible and/or when the clinical

situation does not preclude the use of peripheral sampling. Rationale: Reduces total amount of blood

loss from discards. Reduces risk of contaminated sample due to catheter biofilm. Blood samples

obtained through catheters that are in use are associated with a higher rate of false-positive results,

compared with cultures of percutaneous blood samples (Martinez, et al., 2002) (Mermal,

et al., 2009)

Blood cultures must be drawn using a syringe and a needless transfer device (see

Figure 30). Rationale: The broth from a blood culture bottle directly attached to a

CVC lumen may contaminate the CVC with culture broth.

To Diagnose a suspected CLA-BSI:

Adults and children 12 years of age or older:

o One aerobic Blood Culture set (two green aerobic bottles) be drawn from each lumen of a

suspect CVC)

o One Blood Culture set (two green aerobic bottles) be drawn from a peripheral site.

Note: In some cases, it may not be possible to draw 10 mL of blood. If 5 mL or less is obtained,

place all of the blood into the aerobic (green top) bottle.

(Fraser Health Authority, Test: Blood Culture. MIC 02160, Microbiology, 2009) (Mermal, et al., 2009)

In addition, if the CVC is removed for a suspected CLA-BSI, send the suspect catheter tip (distal

4-5 cm) to the lab in a sterile C&S container for semi-quantitative culture.

Rationale: Peripheral blood draw – High number of false positives if samples only collected

through the CVC as false positive culture can be result of contaminants. Tip culture – Catheter

tip is the final common pathway for colonization of the catheter, leading to catheter-related

bacteremia. (Infusion Nurses Society, 2016) (Mermal, et al., 2009)

72

Removal of Short-Term CVCs and PICCs

Central venous catheters (CVCs) including peripherally inserted central catheters (PICCs) are removed

when therapy is completed, when the catheter’s presence could cause complications (e.g. the catheter

is malpositioned), or when the patient has developed a catheter-related infection. Central venous

catheters should be removed when no longer necessary to decrease the risk of infection. If a line was

placed under non-sterile technique, such as during an emergency, the line should be removed within 48

hours.

POINTS TO REMEMBER BEFORE REMOVAL:

Ensure presence of a physician’s order for removal.

Assess vital signs and neurovascular status of the extremity distal to the catheter insertion

site.

Assess the current coagulation values. (consult physician before removing if patient has

elevated coagulation values, is on anti-coagulants, or has a pacemaker).

Assess the catheter site for signs of infection (i.e., redness, warmth, tenderness, swelling, and

presence of drainage.)

POINTS TO REMEMBER FOR THE REMOVAL PROCEDURE:

Place the patient supine in a slight Trendelenburg position. The level of the catheter site should

be below the heart to prevent air embolus during removal. Place the patient flat if

Trendelenburg is contraindicated or not tolerated by the patient, or if a femoral CVC

will be removed. If the CVC is in the femoral vein, extend the patient’s leg and ensure

that the groin area is adequately exposed.

If removing an internal jugular or subclavian catheter, ask the patient to take a deep breath in

and hold it. This causes a valsalva response. If a valsalva response is contraindicated, such as

with glaucoma or retinopathy, the patient should be asked to exhale during the removal. If

the patient is receiving positive-pressure ventilation, withdraw the catheter during

the inspiratory phase of the respiratory cycle or while delivering a breath via a bag

valve mask device.

Gently withdraw the catheter, pulling parallel to the skin and using a constant, steady motion.

If resistance is met, do not continue to remove the catheter. Notify practitioner

immediately.

As the introducer exits the site, apply pressure with petroleum-based ointment and sterile

gauze (or a petroleum impregnated sterile gauze dressing). The distal end of a multi-lumen

catheter should be removed quickly because the exposed proximal and medial

openings could permit the entry of air.

Upon removal of the catheter, inspect the tip for integrity & length. Place the catheter on a

moisture-proof pad and dispose of properly. If an infusion-related infection is suspected,

a segment of the catheter may be sent for culture. If damage to or fragmentation of

the catheter is observed, additional assessment, such as a chest radiograph, is

warranted.

73

Continue applying firm, direct pressure over the insertion site with petroleum-based ointment

and sterile gauze (or a petroleum impregnated sterile gauze dressing), sealing the site until

bleeding has stopped. Because CVCs are placed in large veins, it may take up to 10

minutes for hemostasis to occur. Pressure may be needed for a longer period of time

if the patient has been receiving anticoagulant therapy or if coagulation studies are

abnormal.

Apply a sterile dressing to the site. Use either a transparent, semi-permeable dressing or

gauze dressing overtop of the petroleum impregnated sterile gauze dressing. If the patient is

diaphoretic or if the site is bleeding or oozing, a gauze dressing is preferred.

Maintain bed rest for at least 30 minutes after catheter removal. Assess the site for signs of

bleeding every 15 minutes times 2, and prn (i.e. every 30 minutes times 2, then 1 hour later as

needed).

Change dressing and assess site every 24 hours after catheter removal until site is

epithelialized.

Infection Control

All staff will follow the latest Infection Control Guidelines for Principles of Infection Prevention

and control, Routine Practices (including hand hygiene, application of personal protective

equipment, and sharps handling and disposal) and Additional Precautions, and blood and body

fluid spills clean-up.

Prior to all procedures, clean dressing cart or bedside table using bactericidal wipes.

Hand hygiene - cleanse hands using hospital approved alcohol hand gel as per Infection Control

protocol.

Mask and wear sterile gloves for all times that the line is opened (e.g. cap change), the site is

uncovered, and with all immunocompromised patients.

All neutral displacement IV caps and injection ports must be cleansed with a 70% Alcohol swab

for 30 seconds and let dry completely prior to accessing.

Positive displacement IV caps are changed q96 hours, after blood draws, or when contamination

is suspected.

CVC dressings are changed q7days and prn.

Routine culture of CVC catheter tips is not recommended.

Blood Cultures:

For the diagnosis of a Central Line Associated Bloodstream Infection (CLA-BSI), it is

recommended that one aerobic Blood Culture set (two green aerobic bottles) be drawn

from each lumen of the suspect CVC AND one Blood Culture set (two green aerobic

bottles) be drawn from a peripheral site

HOWEVER, if the source of sepsis is unknown, samples need to be collected from at least 2

sites; one set drawn percutaneously from a peripheral vein and one set drawn through the CVC.

One set is drawn with two aerobic bottles, the other set with one aerobic and one anaerobic

bottle.

Additionally, with a suspect CLA-BSI, once the CVC is removed send the suspect catheter tip

(distal 4-5 cm) to the lab in a sterile C&S container for semi-quantitative culture (see FH

Laboratories Microbiology Manual).

74

Troubleshooting a Blocked CVC If no blood returns:

Reposition patient

Ask patient to lift arms, cough and perform Valsalva manoeuvre

Ask patient if usually able to aspirate blood from the line

Re-aspirate for blood. If you have free-flowing blood return, proceed with flush

If a cap is present, remove the cap and try to aspirate from a syringe connection directly

with the catheter hub

If line flushes easily, continue with the procedure

If you still have no blood return or difficulty/inability to flush:

Gently attempt to flush with NS

Do not force - if unable to flush – Stop, label line as “BLOCKED/ DO NOT USE” and

notify Physician requesting orders for fibrinolytic.

Competency Assessed RNs on specified care units may administer two doses of fibrinolytic with

a Physician’s Order

If still no blood return or inability to flush ~ label line as “BLOCKED/ DO NOT USE” and notify

Physician immediately.

If air is present (remember to scrub the cap/CVC hub with an alcohol swab for 30 seconds and allowing

to dry before accessing):

Withdraw air from catheter using a syringe

Remove the syringe from the positive displacement IV cap

Expel the air from the syringe.

Insert new syringe with NS and flush.

Remove syringe

Clamp line

Monitoring Central Venous Pressure (CVP) When clinically indicated in a Critical Care area, CVP should be continuously monitored and documented

routinely; on admission, the beginning of every shift and a minimum of q4h and:

- Following a bolus IV fluid or a blood product transfusion

- Following the initiation of vasopressor or vasodilator therapy

- After significant vital sign change

- As per Physician’s Order

Friction scrub the Neutral Displacement IV Cap when accessing through the cap

Friction scrub the CVC hub when removing/changing cap

Always scrub using an alcohol swab for 30 seconds allow to dry completely
